Building a new home or adding on to your existing one? Alleman Roofing & Maintenance handles new roof installation from decking to ridge cap. We work with your general contractor or architect to coordinate scheduling, material selection, and code compliance for your Alleman build.
Our New Roof Installation Process
Plan Review & Consultation
We analyze your plans for pitch, square footage, ventilation needs, and code compliance. You get a detailed proposal with material specs, timeline, and fixed pricing before any work begins.
Pre-Installation Setup
We coordinate delivery timing with your GC so materials don't sit exposed longer than necessary. Our staging crew organizes everything on the roof deck for efficient installation the next morning.
Expert Installation
Installation follows IRC building code and manufacturer requirements. Proper overlap, correct fastener patterns, sealed penetrations, and balanced ventilation. Our crews are factory-trained and know the installation manuals by heart.
Warranty Registration
Final quality check against manufacturer installation requirements. Building inspection coordinated through our Alleman office. Warranty registered directly with GAF, Owens Corning, or CertainTeed.

We install new roofs on new builds every week. Our Alleman crews know the pace, the coordination, and the quality standards that new construction demands.

Factory-certified installation means your new roof warranty is fully backed from day one. No gaps, no exclusions from improper installation.
Ventilation Design
We calculate intake and exhaust per IRC R806 for every new install. Balanced ventilation extends roof life and cuts energy costs. Most contractors skip this step.

About Our Alleman New Roof Installation Services
Proper ventilation is the most overlooked element in new roof installation. We calculate intake and exhaust requirements per IRC R806 based on your attic square footage. Balanced ventilation (soffit intake matched to ridge exhaust) keeps your attic cooler in summer and drier in winter, extending roof life and reducing energy costs.
New roof pricing depends on material choice, roof size, and pitch. Architectural shingles in Alleman run $350-$550 per square installed. Standing seam metal is $12-$22 per square foot. We provide detailed proposals with exact pricing for your specific project.
